You have alot to learn

Babies will lie to you before they can even talk. You say "do you need to go pottie?."

They look you in the eye and shake their head no, and then they crap their pants.

Wait until you have two children and you will see the jealous spite your first child has without being tought.

The Bible says that's our nature. It's the part of us that we have to overcome to be born again and walk the walk.
